Regular maintenance, such as the cleaning of filters, is important for the efficient operation ofresidential ventilation systems. The main objective of this study is to investigate effect of regularmaintenance on fan energy use and ventilation performance by using a test dwelling employingbalanced ventilation system. Experimental tests were directed with simulating the decrease of the airflow rates on terminals. Without cleaning, SFP based on the net air flow rate can indicate by 2.7 times compared with cleaned system.
